What's all this bullshit about Z28 being a "track star" or something "truly special".

Because it was something "truly special".

"What's important to remember about the Z/28 is how unique its mission was. While the rest of the Camaro lineup was designed and built around standard street car parameters (a trait Car and Driver referred to as "a polished lack of character"), the Z/28 was produced to homologate a race car package; the parts selected fell within higher specifications not usually used by Detroit carmakers. By doing so, Chevrolet, unwittingly or not, came close to building one of the best American sports sedans ever made. "With the Z/28," Car and Driver observed, "Chevy is on the way toward making the gutsy stormer the Camaro should have been in the first place."

Hopefully it's a good sign for a Z28 on the 5th gen. I personally was shocked when they chose ZL1 over the name Z28 but the Z28 should probably be a higher performance edition that the SS yet lower & a little less expensive than the ZL1.
